PLOW-BEAM ATTACH M ENT.

. seiicriricA'rioiii fbrmm part of Letters Patent No. 239,735, dated April 5, 1881. A Application filed January 8, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES T. CUNNINGHAM, residing near Egypt, in the county of Chick- V asaw and State of Mississippi, have invented anew and valuable ImprovementinPlow-Beam Attachments; and I do hereby declare that the following is a full, clear-,aud exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specificatiom'and to the letters and figures of reference marked thereon.

Figure l of the drawings is a perspective view, showing the whiffletree attached. Fig. 2 is a perspective view, showing a modified way of attaching the clevis.

This invention has relation to plow-beam attachments; and it consists in theimproved features of construction and combination hereinafter fully described, and particularly pointed outin the claim.

In the drawings hereto annexed, A is the ordinary plow-beam, carrying the share.

B is the auxiliary beam. This is attached to beam A by a belt, a, and is set at an angle thereto, as seen at b.

Between beams A and B is set the bracewedge 0, held in place by a bolt, 0.

To the ends D E of beamsAB are attached the clevises F G, in which are the rings or loops H and I. These clevises are arranged either vertically or horizontally, and when the beams are of iron the ends can be turned at right angles.

K is the whiffletree, having the plate 9 and cuffs h k. The cuff It extends at the rear at l, as well as in front atf. The whifiietree is to be attached to loop I by its plate g, and to loop H by the rear extension, Z, of cuff It. By these means the whiffletree is connected at its middle to the end of beam B and at its inner end to beam A, the distance of these two beams apart or their angle of inclination being determined by the length of the whiffletree. This construction, it will be seen, brings the inner end of the whiffletree on a line with the share, and throws the horse upon the land side.

For double teams, the inner end of the inner whifietree .is attached as described, the double-tree being attached to beam B, the am gle, of course, being varied between the beams. Thus in following both horses'wallr on the unplowed land.

In Fig. 2 the clevis is shown hung under the beam instead of in front.

I am aware that the patent to H. O. Sieverling, No. 110,080, shows a side draft; but the construction therein shown is not claimed 4 herein.

What I claim is- In a plow, the beam A, having its; end D provided with the clevis I in combination with the auxiliary beam B, secured at an angle-to the beam A by the bolts a and o and interposed wedge O, and having the clevis G, and the single-tree K. secured at its middle to the clevis G by the ring I, and at one end by the ringH to the clevis F, substantially as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence.
